Abstract

PURPOSE:To make it possible to use as a panel light source for the lighting of advertisement, a public relation display, and the like, as well as for an ordinary lighting, by furnishing plural zigzag or spiral discharge routes at the discharge lighting portion, and arranging electrodes at both ends of each discharge route. CONSTITUTION:Each unit display discharge lamp 20 is composed of a front panel 1, an insulating rear panel 2 consisting of a glass with a spiral discharge route a placed in a matrix form and the like, electrodes 3, a barrier 4 (partition wall) fixed to partition the discharge route and to improve the anti-vacuum- pressure property, a linking way 5 to seal a discharge medium (a gas), an air hole 6 to exhaust each display charge lamp and seal a gas, an exhaust gas sealing member 7, an electrode lead-in line 8, a terminal 9 for the electrode lead-in line, and a phosphor layer 10 to display plural colors. The unit display discharge lamps 20 are arranged in a matrix form. By connecting an AC power source to a lateral all-circuitlinking line and to a longitudinal all-circuit-linking line at a time, all the unit display discharge lamps are lighted simultaneously, and a panel light source for the ordinary lighting is made up.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a panel-type discharge lamp that can be used not only for general indoor and outdoor lighting, but also for advertising lighting and public relations displays.

[Conventional technology and its problems]

Various attempts have been made to develop panel light sources, but they have not yet been put to practical use.

As a prototype flat light source, a flat light source using a flattened fluorescent lamp tube is being considered, but since the discharge operates under minimum energy conditions, plasma will not spread and form within the flattened tube. Therefore, a flat light source has not been realized yet.

Conventionally, light bulbs and neon tubes have been widely used for indoor and outdoor advertising lighting and public relations displays, but these light source lamps have the following drawbacks.

[1) A large number of different types of mounting devices are required.

(2) A large mounting area is required, such as the depth of the mounting position.

(3) Equipment and maintenance costs are expensive.

(4) Many types of light source lamps are required for display.

(5) Utilization efficiency for lighting and display is poor, and power consumption is large.

SUMMARY OF THE INVENTION Therefore, the present invention provides a panel discharge lamp that can be used as a panel light source for general lighting, and can also be used for advertising lighting, public relations displays, etc. by changing the power supply method.

[Means for solving problems]

The present invention was made to solve the above-mentioned problems, and
A plurality of discharge paths are provided in a discharge light emitting portion in a zigzag (meandering) shape or a spiral shape, and electrodes are provided at both ends of each discharge path.

[For production]

By adopting a method of supplying power to each electrode simultaneously,
It can be used as a panel light source for general lighting, and by intermittent control of the power supplied to the electrodes provided in each unit discharge path, it can be used as a panel light source for advertising lighting and public information displays.

Therefore, it is possible to provide a large-screen panel display device not only for indoor use but also for outdoor use, which has been completely unthinkable in the past.

Embodiments of the present invention will be described below based on the drawings.

〔Example〕

FIG. 1 is a partially cutaway plan view of a one-panel discharge lamp according to the present invention in which spiral discharge paths a are arranged in a matrix, and FIG. 2 is a cross-sectional view taken along line A-A in FIG. 2 is a front glass substrate, 2 is an insulating back substrate made of glass or the like with spiral discharge paths a formed in a matrix, 3 is an electrode, and 4 is a fixed barrier to partition the discharge path and increase the vacuum withstand voltage. ), 5 is a communication path for sealing in a discharge medium (gas), 6 is a ventilation path for exhausting each display discharge lamp and filling in gas, 7 is an exhaust sealing part, 8 is an electrode lead-in line, Reference numeral 9 represents an electrode lead-in wire terminal portion, and reference numeral 10 represents a fluorescent material layer for multicolor display.

Note that the cross-sectional area of the communication path 5 is 175 times or less of the cross-sectional area of the ventilation path 5.

FIG. 3 shows an example of circuit connection when the unit display discharge lamps 20 configured as described above are arranged in a matrix, where 3 is an electrode, ! ,...X, and yI...
・Y is the vertical and horizontal circuit connection wiring, and 30 is the load resistance.

The panel discharge lamp configured as described above has horizontal all-circuit connection wiring X,...X, and vertical front circuit connection wiring y,
... 73, all unit display discharge lamps 20 are lit at the same time, and serve as a panel light source for general illumination.

Furthermore, by selecting vertical and horizontal circuit connection wiring and connecting a power supply between them, it can be used as advertising lighting or a public relations display screen.

Although the panel-type discharge lamp described above has an integral structure in which the unit display discharge lamps 20 are arranged in a matrix, the unit display discharge lamps may be connected.

That is, a unit display discharge lamp 2 constructed as shown in FIG.
1 may be arranged vertically and horizontally in a mosaic pattern to form a large panel discharge lamp.

FIG. 5 is a sectional view of a different embodiment of the unit display discharge lamp in which the discharge path a' is formed in a spiral shape, and FIG. 6 is a sectional view of a unit display discharge lamp in which the discharge path a'' is formed in a zigzag shape.

Since the panel-type discharge lamp according to the present invention has a back part composed of an insulating back substrate 2, as shown in FIG.
By providing this, mercury pressure can be easily adjusted when mercury vapor is used, and a panel light source for cold regions can be provided.

〔Effect of the invention〕

According to the present invention, it is possible to provide a panel light source for general illumination for indoor and outdoor use, and an excellent advertising lighting and public information display device.
